[Caleb]

aalt fermi tutti ci sono arrivato... avevo cannato il nome di una variabile, ora funzia

<?
include "db_connect.php";
$nick = $_POST['nick'];
$pwd = $_POST['pwd'];
$pwd_md5 = md5($pwd);
?>
<div id="centerbox">
        <?php
        $cookienick = $_COOKIE["nick"];
        $cookiepwd_md5 = $_COOKIE["pwd_md5"];
        echo "Cookienick e` $cookienick, Cookiepwd_md5 e` $cookiepwd_md5";
        ?>
    </div>
<?php
if (($nick!="") && ($pwd!="")) {
    $q_login=mysql_query("SELECT * FROM users WHERE nick='$nick' AND password='$pwd_md5'");
    $q_login_count=mysql_num_rows($q_login);
    if ($q_login_count==1) {
        setcookie("nick", $nick);
        setcookie("pwd_md5", $pwd_md5);
    }
    else {
        ?>
        <div id="centerbox">
            Utente o password errati, [url="login.php"]riprova[/url]
        </div>
        <?php
        }
}
else {
    ?>
    <div id="centerbox">
        <h2>Login utente</h2>
        <form action="login.php" method="post" id="formadmin">
            <table>
